dpo 8 ...

I've been having mild period like cramping since dpo4 which is unusual ... and now increased watery cm which I typically get before AF and now my lower back is aching ... my AF is due in 6 days. I'm tempted to test in few days but at the same time, what's the point even tho I feel like AF will come anyway? I know I'm not out til AF shows up. I hate 2ww. this time around, we did mucinex. TTC for 3 years :/
